nice -- execute a utility with an altered scheduling priority SYNOPSIS
nice [-n increment] utility [argument ...] DESCRIPTION
nice runs utility at an altered scheduling priority. If an increment is given, it is used; otherwise an increment of 10 is assumed. The super-user can run utilities with priorities higher than normal by using a negative increment. The priority can be adjusted over a range of -20 (the highest) to 20 (the lowest). Available options: -n increment A positive or negative decimal integer used to modify the system scheduling priority of utility. DIAGNOSTICS
The nice utility shall exit with one of the following values: 1-125 An error occurred in the nice utility. 126 The utility was found but could not be invoked. 127 The utility could not be found. Otherwise, the exit status of nice shall be that of utility. COMPATIBILITY
The historic -increment option has been deprecated but is still supported in this implementation. SEE ALSO
csh(1), getpriority(2), setpriority(2), renice(8) STANDARDS
The nice utility conforms to IEEE Std 1003.2-1992 (``POSIX.2''). HISTORY
A nice utility appeared in Version 6 AT&T UNIX. BUGS
nice is built into csh(1) with a slightly different syntax than described here. The form 'nice +10' nices to positive nice, and 'nice -10' can be used by the super-user to give a process more of the processor. BSD

nice -- execute a utility at an altered scheduling priority SYNOPSIS
nice [-n increment] utility [argument ...] DESCRIPTION
The nice utility runs utility at an altered scheduling priority, by incrementing its ``nice'' value by the specified increment, or a default value of 10. The lower the nice value of a process, the higher its scheduling priority. The superuser may specify a negative increment in order to run a utility with a higher scheduling priority. Some shells may provide a builtin nice command which is similar or identical to this utility. Consult the builtin(1) manual page. ENVIRONMENT
The PATH environment variable is used to locate the requested utility if the name contains no '/' characters. EXAMPLES
Execute utility 'date' at priority 5 assuming the priority of the shell is 0: nice -n 5 date Execute utility 'date' at priority -19 assuming the priority of the shell is 0 and you are the super-user: nice -n 16 nice -n -35 date DIAGNOSTICS
If utility is invoked, the exit status of nice is the exit status of utility. An exit status of 126 indicates utility was found, but could not be executed. An exit status of 127 indicates utility could not be found. SEE ALSO
builtin(1), csh(1), idprio(1), rtprio(1), getpriority(2), setpriority(2), renice(8) COMPATIBILITY
The traditional -increment option has been deprecated but is still supported. STANDARDS
The nice utility conforms to IEEE Std 1003.1-2001 (``POSIX.1''). HISTORY
A nice utility appeared in Version 4 AT&T UNIX. BSD
